PROPELLING AND STEERING APPARATUS.

Specification of Letters Patent No. 22,431, dated December 28, 1858.

To all whom fit may concern:

AMUEL I-IUSE, J r., of Chicago, in the county of Cook and State ofIllin'ois, have invented certain Improvements in Combined Propeller andSteering Apparatus, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, makingpart of this specification, in which- Figure l, is a side elevation.Fig. 2, a plan, a portion of the deck being broken away to show theparts beneath.

It has already been proposed to hang Propellers in a frame capable ofswinging around the rudder post in such a manner that the propellermight be made use of to steer the ship. No adequate means have howeverbeen adopted of supporting the shaft of the propeller or of receivingand resisting its end thrust, and consequently such arrangement hasfailed to be of any practical value.

Our invention has for its object the accomplishment of this desirableend, that is to effect the steering of the vessel by the propelleritself, which we accomplish in a manner which will now be fully setforth and described.

In the accompanying drawings A, is the deck of the vessel; B, a verticalpost which is held firmly up to the stern post H, by straps Z. To thispost is suspended by similar straps X, the rudder C, which is enlargedas at C2 so as to form a frame within which revolves the propeller D,and in which is boxed both ends of its shaft This shaft carries at itsinner extremity a gear E, that is driven through the intermediate gearF, by a similar gear G, upon the engine shaft g.

Then the propeller is in operation a great end thrust is exerted in thedirection of the arrow Fig. l, and for the purpose of resisting thisthrust and effectually preventing the parts from being strained andthrown out of position thereby, the following device is employed. Thepost B, is caused to bear upon the stern post I-I, the whole of itslength except where the latter is necessarily cut away to accommodatethe lto the staple 7L.

gears G and F. The portion of the shaft thus left unsupported issurrounded by a sleeve I, against which the end of the shaft f isallowed to bear; the whole end thrust of this shaft is thus transferredto the sleeve, and through the post B to the stern H. The sleeve beingof a thickness and strength that will enable it to resist any pressurethat can be put upon it by the shaft f, and of a length nearly equal tothe opening in the stern post H, so that the thrust is received by thepost B, in the immediate vicinity of its bearing on the stern post. Allstrain is thus taken off the gearing which is left free to revolvewithout restraint.

lhen the rudder is directly fore and aft the propeller will act only asa propeller to urge forward the vessel but whenever the rudder isinclined to either side, if the propeller be in action it will alsosteer the vessel to the side to which it is inclined. For the purposethus of moving the rudder the following device is employed: Projectingrearward from the rudder is a tiller K, to which is secured a beam L,the exterior surface mi, of which is the arc of a circle the center ofwhich is the center of the post B. The beam L, is further stayed andsustained by the side bars M.

O, is a cylindrical indiar rubber spring through the center of whichpasses the tiller K. This spring is contained within a rectangular boxor case S, to the ends of which are secured the staples 71, i, to whichare attached the ends of the tiller rope or chain P. This rope or chainstarting from the staple h, passes over the guide pulley a, along theedge mi, of the curved timber L, beneath the pulley b, and over thepulley (l, thence to a suitable steering wheel at R (not shown in thedrawing) thence over the guide pulley z' and beneath the pulley n,thence over the curve m, round the pulley r, It is obvious from theabove that the spring O is interposed between the tiller K, and eitherend of the box S, to which is secured the chain P, and the steeringapparatus is relieved from the heavy blows and shocks to which therudder is subjected by the waves. The staples h 7L are furnished withnuts y, upon their shanks of the propeller shaft. upon the sleeve I on.2 i by which the slack of the tiller rope is taken the post B, arrangedand operating in the l u 3. manner substantially as described. r

The rudder may thus be operated as re- SAML. HUSE. if 5 quired by thehelmsman in his ordinary SAML. HUSE, Jn. ,f
